Dynamism
Dynamism is something which many medical students and doctors forget. It is the concept that scenarios and situations are forever changing, and the best interests or ideal decisions made at a particular time may not apply at a later time.

Care should always be taken when considering what the best course of action should be. Not doing anything can sometimes be ideal. As one famous saying goes, "It is better to do nothing than to do what is wrong". It may be that the decisions become easier to make when one returns to a problem or situation later on, or more often, that patients change their minds once they have had time to digest the information given to them, or when their disease process has progressed.

Try not to forget about dynamism.
